A plug for an osmometry sample cup or vial is provided that seals the sample cup or vial to prevent significant evaporation of a sample solution in the cup or vial prior to obtaining an osmolality measurement.

Plug for osmometry sample cup

A temperature control device and method are provided for an analytical system for performing laboratory protocols. The device includes a well within a housing configured to receive a biological specimen according to a predetermined sample process. The specimen is suspended by a holding device in the well. A thermal element is provided in heat exchange communication with fluid in the well. A temperature sensor is located in the well at a location to be covered and uncovered by rocking motion of fluid in the well. A controller, in communication with the thermal element, the temperature sensor, and an agitation system, is operative to control the thermal element in correlation with temperature data, for example, peak temperature data, from the temperature sensor.

A centrifugal assembly is provided that can be used in common laboratory fixed angle or swinging bucket centrifuges for the separation of material, such as parasitic ova, based on particle density. The centrifugal assembly allows the fluid level to be gently adjusted to form a meniscus without disruption of the buoyant matter, such as ova. The centrifugal assembly also enables a user to easily and hygienically collect and transfer a measured amount of a sample, such as fecal material, and to break apart and mix the sample with a floatation fluid contained in a centrifuge tube.

Centrifugal assembly and method for ova detection

A rotor is provided for the centrifugal separation of a composite fluid, such as animal or human blood, into components. An inner surface of the rotor includes at least one hydrophobic area having a first surface energy sufficiently low to provide a flow path for a lower density fluid component to flow to the bottom of a central collection chamber after centrifugal separation. A method of separating a composite fluid into components using such a rotor is also provided. Additionally, a method of manufacturing such a rotor is provided.
